Man what a thread!
Linux is good, Windows is also good.
It all boils down to Your Personal Preference. Use what you like.
Linux does require more from the user than sticking a disk in the drive and pressing enter. Windows can require more also but, usually not near as often on initial set-up.
Once Linux is set-up / configured using KDE Desktop a Windows user could probably walk right in and use it just fine. Gnome Desktop is a little more problematic for a Windows user to get ahold of.
Linux is NOTHING like it was say 12 - 13 years ago... then you really did have to know something. Now it is a snap in comparison. The same goes for Windows ...compare Windows XP to say Windows 3... Big Difference.
I say if you want to learn something use Linux. If you want to use it and nothing more use Windows.
I use both!
